I'm sure they probably believe what they've stated. But I have no idea of the veracity of their source, the content of the information the source passed on or the context under which the source received the information.

There's to much information out there based on 'sources' for me to give too much, if any, credence to that information without knowing more.

And I understand that I might never know more. But that doesn't mean I'm going to believe everything that gets posted here.
